Haystack Butte Jellybean Jasper Slab — PP-00005
A hand-collected jellybean jasper slab from Haystack Butte in the Owyhee high desert of southeast Oregon. I prospected this piece myself, hauled it home, and slabbed it on my own lapidary equipment.
About this piece
Jellybean jasper is a brecciated jasper made up of rounded, bean-shaped jasper clasts in a chalcedony matrix — the "jellybeans" are individual jasper pebbles in red, yellow, orange, and brown that got cemented together and silicified into a single stone over geologic time. This slab shows the jellybean structure clearly across both faces, with a strong color range of deep red, vivid yellow, orange, plum, and grayish-blue zones.
One of the standout features of this piece is its translucency. Hold it up to a light and the chalcedony matrix between the jasper beans passes light cleanly, while the denser jasper clasts stay opaque — a backlit effect that not every jellybean slab shows, and a real selling point for cabbers who want to feature it in pendants or wearable work.

- Dimensions: 3.75" × 2.25" × .375"

For cabbers
A solid 1/4" thick — good working thickness for standard cab doming. Plenty of material here for multiple cabs cut to feature different bean clusters, or a single larger cab that captures the full color range. Jellybean jasper takes a beautiful polish and the color zones hold up well at the lap. Standard stability practices apply — inspect any visible fractures with a loupe and stabilize before cutting if needed.
Piece is lightly coated in 100% food-grade mineral oil.
About Plume & Prospect
Plume & Prospect is a one-person operation run by a working prospector in southwest Idaho. I'm a prospector first — chasing gold, minerals, and rough across the Owyhee high desert — and I rockhound everything beautiful I come across along the way. Every single piece in this shop is a specimen I personally gathered in the field, then brought home and worked by hand on my own lapidary equipment. I'm not a reseller. I don't import rough from overseas, I don't buy at shows and flip it, and I don't sell anything I didn't pull out of the ground myself. If it's in the shop, I prospected it, I cut it, and I can tell you exactly where it came from.
